Returns and Repairs.

You may visit Len Wallis Audio and a staff member will assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be repaired, or providing you with a replacement.

Goods must be returned within a reasonable time. 

If any goods cannot be easily returned to us due to their size, the fault or because they have been affixed or installed in your premises, please contact us and we will arrange an inspection to assess the goods.

Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be provided with an indicative repair time, which time may vary due to reasons beyond ours or the repairer’s reasonable control, such as part availability and incorrect fault description.

You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident, or where your rights under the Australian Consumer Law or any manufacturer’s warranty do not apply. We may provide you with an indicative fee, which may vary due to reasons beyond our control.

If any goods that you return are capable of retaining user generated data such as files stored on a hard drive, and songs stored on a portable media player, the replacement or repair of the goods may result in loss of the data. In these circumstances, we recommend you back up data to prevent data loss, and remove sensitive or confidential data, as a party assessing and/or repairing your goods may be required to view data in the course of carrying out the assessment. We will not be responsible for any data loss.

In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
